The invention is applicable to the technical field of biological
medicine, and provides a self-assembled
drug molecule and a preparation method and application thereof, and the preparation method comprises the following steps: synthesizing a compound Py-S-S-COOH; the method comprises the following steps: synthesizing a compound Py-S-S-B1RA; synthesizing a
compound A; synthesizing a compound B; synthesizing a
compound C; synthesizing a compound D; synthesizing a
compound E; synthesizing a compound F; and the compound CBT-Gem-B1RA is synthesized through the synthesis of A chemotherapeutic
drug gemcitabine and a targeted
peptide bradykinin B1
receptor stimulant are coupled with
a peptide fragment with self-
assembly performance, so that the molecule has the capabilities of penetrating a
blood brain barrier and targeting
brain glioma, can smoothly enter a
brain glioma part and can be self-assembled into nano particles in
brain glioma cells, and the nano particles can be used for preparing a
drug for treating brain
glioma. The
residence time of the drug in
tumor cells is prolonged, the drug enrichment concentration is increased, and finally the
glioma specific
targeted therapy is realized.
